Each lateral extension 30 and 31 cation of cross head guides of the Laird type. is provided with a horlzontal flange 32, a In the practice of the invention, referring vertical flange 83, and a boss 34a, the flanges descriptively to the specific embodiment and bosses being provided with suitable thereof which is herein exemplified, the comholes 3 1 for bolting the bed to the slde frame members 11. Each of the lateral extensions is also provided with a pocket for the reception of one of the suspension links 14.

The space between the lateral extensions on each side of the longitudinal beam 29 provides a pocket 36, for a lateral motion lever 21. Each side wall 88 of each lever pocket is provided with a cylindrical socket or bearing 89 for the reception of one end of one of the fulcrum shafts 22, and the rear wall of each pocket is formed with a stop boss for limiting movement of the lever.

The front of the bed is formed with a transverse vertical flange 4L1, having bolt holes 42 for fastening the bed to the flange 43 of the frame cross-tie member 20, which cross-tie member may be joined, if desired, to a rear extension from a cylinder saddle in accordance with well-known practice.

The front transverse beam 27 comprises a transverse vertical wall 4.4, joined at its bottom to the bed 26, two spaced transverse horizontal walls 45 joined to the vertical wall 4-1, and two longitudinal vertical walls 46, one disposed adjacent each end of the beam and joined to the transverse vertical wall 44;, and the spaced transverse horizontal walls 45. Each end of the vertical wall 44 is provided with bolt holes 47., for the attachment of a guide yoke 25a for the piston red cross head guides 19, and the front end of one of the valve motion supports 2%.

The rear transverse beam 28 comprises a transverse vertical wall 51 joined at its base i to the bed 26, two spaced transverse horizontal walls 52 joined to the vertical wall 51, and two longitudinal vertical walls 53, one at each end of the beam and joined to the walls 51 and 52 thereof. Each longitudinal wall 53 is provided with belt holes 54: for the attachment of the rear end of one of the valve motion supports 24. The transverse vertical wall 51 is provided adjacent each end with a pair of rearwardly projecting spaced lugs 55 which serve as stops for limiting rotatory movement of the reverse shaft 16, a boss 56, having bolt holes 57 for the attachment of the reverse shaft bearing member 25, and bolt holes 58 for the attachment of a boiler waist plate 18.

Each guide yoke 25a is provided at its top with a vertical flange 59, having bolt holes (30 for the attachment of one of the boiler waist plates 18.

, having bolt holes 62 for the application of a cross head guide of the Laird type.

\Vhile one of the preferred forms of construction has been shown, it is obvious that many variations in procedure, form, ar-

rangement, and construction of the parts can be made, and the invention is not therefore limited to the particular embodiment disclosed, but includes such changes and modifications as come within the spirit and scope of the invention as set forth in the appended claims.

The invention claimed and desired to be secured by Letters Patent is:

1. A cross-tie member made as an integral casting having means for securing it to the side frame members of a locomotive and comprising a box-shaped structure having a portion narrowed transversely to provide oppositely disposed spaces, said transversely narrowed portion being thickened vertically to add strength to compensate for loss in strength caused by said narrowing of the casting.

2. In a structure of the character described, the combination of a cross-tie member made as an integral casting having means for securing it to the side frame members of a locomotive, and comprising a box-shaped structure having a portion narrowed transversely to provide oppositely disposed spaces for lateral motion device levers, said transversely narrowed portion being thickened vertically to add strength to compensate for loss in strength caused by said narrowing of the casting; and supports in said spaces for said lateral motion device levers carried by said casting.

8. In a structure of the character described, the combination of a cross-tie member made as an integral casting having means for securing it to the side frame members of a locomotive, and' comprising a box-shaped structure having a portion narrowed transversely to provide oppositely disposed spaces, said transversely narrowed portion being thickened vertically to add strength to compensate for loss in strength caused by said narrowing of the casting; means on the opposite sides of said casting member at said narrowed portion for supporting lateral motion device levers; and lateral motion device leyers in said spaces, carried by said supporting means.

4. In a structure of the character described, the combination of a cross tie member made as an integral casting having means for securing it to the side frame members of a locomotive, and comprising a box-shaped structure having a portion narrowed transversely to provide oppositely disposed spaces for lateral motion device levers, said transversely narrowed portion being thickened vertically to add strength to compensate for loss in strength caused by said narrowing of the casting; supports in said spaces for said lateral motion device levers, carried by said casting; and stops in said spaces for said lateral motion device levers, carried by said casting.
